### CXF方式开发和部署webservice应用 ###

*  1.环境配置
 *  2.创建webservice工程
 *  3.书写服务端代码
 *  4.配置文件
 *  4.启动服务，查看wsdl
 *  5.客户端调用测试
 *  其他

需要项目源码的可以去我的资源里下载

# 1.环境配置 #

1.下载cxf，本例使用的是apache-cxf-2.4.2  
2.配置环境变量  
a)配置CXF\_HOME，值为cxf的安装路径

c)配置classpath，添加%CXF\_HOME%\\lib\\cxf-manifest.jar;

# 2.创建webservice工程 #

1.创建web工程  
2.导入CXF依赖jar包

# 3.书写服务端代码 #

1.接口类

package com.origin.webservice;
    
    import java.util.List;
    import javax.jws.WebParam;
    import javax.jws.WebResult;
    import javax.jws.WebService;
    import com.origin.bean.User;
    
    @WebService
    public interface UserService {
    	@WebResult(name="UserName")String findUserNameById(@WebParam(name="UserId")String UserId);
    	
    	@WebResult(name="User")User addUser(@WebParam(name="User")User u);
    	
    	List<User> findUserList();
    }

**注意：@WebService注解是必须的，其他注解有兴趣可以研究下**  
2.实现类

package com.origin.webservice.impl;
    
    import java.util.ArrayList;
    import java.util.List;
    import javax.jws.WebService;
    import com.origin.bean.User;
    import com.origin.webservice.UserService;
    
    public class UserServiceImpl implements UserService {
    
    	private List<User> userList = new ArrayList<User>();
    
    	public String findUserNameById(String UserId) {
    		for (User user : userList) {
    			if(user.getUserId().equals(UserId)){
    				return user.getUserName();
    			}
    		}
    		return "用户不存在!";
    	}
    
    	public User addUser(User u) {
    		userList.add(u);
    		return u;
    	}
    
    	public List<User> findUserList() {
    		return userList;
    	}
    }

3.接口中测试的User类

package com.origin.bean;
    
    public class User {
    
    	
    	private String UserId;
    	private String UserName;
    	private int UserAge;
    	public String getUserId() {
    		return UserId;
    	}
    	public void setUserId(String userId) {
    		UserId = userId;
    	}
    	public String getUserName() {
    		return UserName;
    	}
    	public void setUserName(String userName) {
    		UserName = userName;
    	}
    	public int getUserAge() {
    		return UserAge;
    	}
    	public void setUserAge(int userAge) {
    		UserAge = userAge;
    	}
    	public User() {
    		super();
    	}
    	public User(String userId, String userName, int userAge) {
    		super();
    		UserId = userId;
    		UserName = userName;
    		UserAge = userAge;
    	}
    	@Override
    	public String toString() {
    		return "User [UserId=" + UserId + ", UserName=" + UserName + ", UserAge=" + UserAge + "]";
    	}
    }

# 4.配置文件 #

--------------------

**注意：配置文件路径都在WEB-INF下**

--------------------

1.web.xml

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
    	<display-name>CXF_WebService</display-name>
    	<servlet>
    	  	<servlet-name>cxf</servlet-name>
    	  	<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    		<load-on-startup>1</load-on-startup>
    	</servlet>
    	<servlet-mapping>
    		<servlet-name>cxf</servlet-name>
    		<url-pattern>/service/*</url-pattern>
    	</servlet-mapping>
    </web-app>

2.cxf-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws"
    	xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:cxf="http://cxf.apache.org/core"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans 
              http://www.springframework.org/schema/beans/spring-beans.xsd
                http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd
                http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd
                http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd">
    	
    	<import resource="classpath:META-INF/cxf/cxf.xml" />
    	<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
    	<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
    	
    	
    	<jaxws:server address="/userservice" serviceClass="com.origin.webservice.UserService">
    		
    		<jaxws:serviceBean>
    			<bean class="com.origin.webservice.impl.UserServiceImpl"></bean>
    		</jaxws:serviceBean>
    		<jaxws:inInterceptors>
    			<bean class="org.apache.cxf.interceptor.LoggingInInterceptor"></bean>
    		</jaxws:inInterceptors>
    		<jaxws:outInterceptors>
    			<bean class="org.apache.cxf.interceptor.LoggingOutInterceptor"></bean>
    		</jaxws:outInterceptors>
    	</jaxws:server>
    </beans>

一个服务对应一个jaxws:server节点，serviceClass=“com.origin.webservice.UserService”，指定接口类，jaxws:serviceBean指定实现类，Interceptors指定拦截器。

# 4.启动服务，查看wsdl #

wsdl地址：http://localhost:8080/CXF\_WebService/service/userservice?wsdl

# 5.客户端调用测试 #

1.本例使用wsdl2java生成客户端代码  
![在这里插入图片描述][20190907135731607.png]\-d 指定生成路径  
\-p 指定package  
代码路径：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2E5NzQ5ODYwNDI_size_16_color_FFFFFF_t_70 3]  
2.将代码复制到工程中  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2E5NzQ5ODYwNDI_size_16_color_FFFFFF_t_70 4]  
3.调用服务

package com.origin.client;
    
    import java.util.List;
    import javax.xml.ws.Holder;
    import org.junit.Test;
    
    import com.origin.wsdl2java.User;
    import com.origin.wsdl2java.UserServiceService;
    
    public class UserClient {
    
    	UserServiceService uss= new UserServiceService();
    	@Test
    	public void addUserClient(){
    
    		User user = new User();
    		user.setUserId("16630");
    		user.setUserName("陈雪松");
    		user.setUserAge(18);
    		Holder<User> u = new Holder<User>(user);
    		uss.getUserServicePort().addUser(u);
    		System.out.println("添加成功!");
    	}
    	
    	@Test
    	public void findUserNameByIdClient(){
    		
    		String username = uss.getUserServicePort().findUserNameById("16630");
    		
    		System.out.println("查询信息:"+username);
    	}
    	
    	@Test
    	public void findUserListClient(){
    		List<User> userList = uss.getUserServicePort().findUserList();
    		for (User user : userList) {
    			System.out.println(user);
    		}
    	}
    }

# 其他 #

CXF 提供了很多拦截器，也支持自定义拦截器，也是很核心的内容，充分体现了AOP切面思想，同样，遇到要用了再做研究
